Deprive the oligarchs and Putin loses pretty quickly. Sure, Russia can engage in some trade with China but there are a list of things that can be done economically.
Close SWIFT to Russia and Belarus
Western and allied nations expel all Russian nationals and deny them re-entry rights until Putin is ousted. (Like Miami winters? Too bad you will be in Moscow. Buy a good coat!)
The above nations freeze all bank accounts, seize property (homes, super yachts, private jets, mistresses’ apartments, etc.) and threaten to nationalize or sell off corporate assets like steel mills and aluminum foundries.
Get MBS to crank up oil production. Allied nations stop purchasing Russian crude.
Iran! Trump and Bebe are not around any longer. How about we resurrect that nuclear deal and you sell all of the oil that you can pump!
Of course, if Vlad suffers an untimely illness and tragically passes on, and you select a far more moderate and pragmatic leader, then we welcome you back, return your stuff, approve Nord Stream 2, and you get to join the G-8 again.
Think it over? I bet we can solve all of these little misunderstandings by June 1.
